, in s, and the like.

he primary ob'ect' of this invention is to provide a genera y improvedcleaning and polishing machine for the purposes above mentioned whichwill be exceedingly simple in construction, cheap of manufacture, andefiicient in.use.

A further and ver important object is inder or drum type in which thecharging and discharging operations may be carried out continuousl durinthe rotation of the cylinder, toget er wit improved means whereby whenthe cylinder or drum is rotated in one direction the parts or materialbeing cleaned and polished willbe subjected 'to the necessary attritionand when rotated in an opposite or reversed direction will be dischargedtherefrom.

Y A still further objectis the provision of a machine of this classadmirably ada ted to receive and carry a suitable supply 0 cleaning andpolishing material, such for ex: ample,as sand and water, together withimproved means for aggregating the material and treating medium forattrition when rotated in one direction and for separating anddischarging the completely treated material from the treating mediumwhen driven or rotated in a reversed direction.

With the 'abovementioned and other ends in view, my invention consistsin the novel construction, arrangement and combination of parts,hereinafter described, illustrated in one of'its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Referring to the drawings, forming a part of this specifcation, Figure 1is a central longitudinal sectional view of a machine constructed inaccordance with this invention, the articles or material being treatedand the treating medium being aggregated for cleaning and olishing byattrition in the tumbling cylin er as the latter is rotated in onedirection for this purpose.

Fig. 3, a cross sectional view of the same, taken on line 3-3 of Fig.'1.

A Fig. 4, a horizontal longitudinal sectional view, taken on line 44.-oFig. 1.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The tumbling cylinder or barrel 1 may be mounted and rotated in anysuitable and convenient manner, as for example,-by meansof su rtingrollers 2, mounted on suitable sha s 3, the latter bein carried in asuitable supporting frame 4. l he cylinder or barrel 1 may be providedwith the usual track-ways or rings 1, and, in thepresent instance, thecylinder or barrel 1 is adapted to be driven t rough the medium of asurrounding sprocket. ring 1", adapted to receive and be driven by asuitable sprocket chain (not shown) leading to a suitable source ofpower.

The receiving end or head of the cylinder 1 is provided with a centralor axially located charge receiving opening 1 through which the materialor articles 5, to be treated are introduced, preferably through themedium of a suitable feed or charging chute 6. The tumbling cylinder 1is provided with a suitable conveyer, preferably in the form of aspirally arranged conveyer blade 7, and the inner periphery of thecylinder is also preferably provided with a series of transverse liftingmembers or slats 8. The arrangement of the conveyer blade 7 is such thatwhen the barrel or cylinder 1 is driven or rotated in the direction ofthe arrow marked A, the articles 5 being treated and the treatingmedium, such as sand as shown,

will be aggregated along the receivin por-' tion or section of thetumbling cylin er, as shown most clearly in Fig. l'of the drawmgs.

As a means of segregatin and discharging the articles or materia beingtreated when subjected to the necessary attrition, and u on a reverserotation of the cylinder, as in icated by the arrow marked B, thecylinder 1, in the present instance, is pro vided with an intermediatewall 1, having a central or axially located discharge opening 1, thelatter being provided with a transfer device in the specific form of adischarge chute 9, provided with a mouth or receiving portion 9, thelatter being preferably formed by means of a vane or bafiie 9",extending to the outer wall of the tumbling cylinder 1 at the dischargeportion of the latter and being adapted to intercept and pick up anddivert the finished material as received from the conveyer 7 as asegregatrating and discharging the finished materia as thus segregatedand delivered through said chute 9 during the reverse or dischargingrotation of the cylinder, the discharge opening 1 is preferably providedwith a concentrically located article separating and dischargingcylinder 10, of suitable pervious or foraminous material, such as wireas shown, said discharging cylinder being provided with a spiralconveyer 10.

As a means of causing the treating medium, such as sand and water, orthe like, to return to the tumbling cylinder and to be maintained in thelatter at substantially a c0n stant level, the discharge portion of thecylinder is preferably arranged to inclose the major portion of theseparating cylinder 10 and the head 1, is preferably provided about itsperiphery with a series of openings 1 adapted to permit thecleaningliquid or Water to discharge or drain into the discharge tank 11. v

The tumbling cylinder or barrel 1 may be supplied with liquid by meansof a suitable pump 12, communicating with suitable receiving anddischarging pipes 13 and 14, respectively, communicating with the tank11, and the charge receiving opening 1.

In View of the above described construction and arrangement of parts, itwill be obvious that when the tumbling cylinder or barrel 1 is rotatedin the direction of the arrow marked A the articles 5 to be cleaned andpolished and the cleaning medium, such as sand, will be held toward thereceiving and charging end of the cylinder, by the reverse rotation ofthe conveyer 7 and it will also be apparent that immediately upon thereversal of the direction of rotation of tho tumbling and separatingcylinders 1 and 10, and the intermediate transfer device or chute 9 theconveyer blade 7 will carry the articles or material being treatedtoward the intermediate wall 1 and the articles striking or beingintercepted by the vane or bafile 9" forming the mouth 9 of the chutewill be thus segregated and directed into the feed end of the ,articleseparating and discharging cylinder 10.

Having thus described one of the embodiments of my invention, withouthaving attempted to set forth all the forms in which it may be made, orall the modes of its use, what I claim and desire to secure by LettersPatent, is

1. In a cleaning and polishing machine, a

rotatabl mounted imperforate cylinder provide at one end with conveyermeans adapted when said cylinder is rotated in one direction toaggregate the material and treating medium near the feed end thereof andprovided with means for segregating the material being treated when thecylinder is rotated in the other direction, a concentric cleaningcylinder enclosed b and communicating with said tumblin cy inder, and atransfer device between sai tumbling and cleaning cylinders constructedand arranged to en age and transfer the segregated material to saidcleaning cylinder.

2. In a machine of the character described, a (pair of rotatably mountedimperforate an perforate tumblin and separating c linders, respectively,said tumbling cylin er being provided with an axially located articlereceiving opening at one end and provided on its interior with means forkeeping the articles being treated aggregated near said receivingopening when the c linders are rotated in one direction, an means withinsaid tumbling cylinder for separating the articles being treated fromthe cleaning material and discharging the same into said separatingcylinder when said cylinders are rotated in the other direction.

3. In a machine of the character described, a pair of rotatably mountedimperforate and perforate tumbling and separating cylinders,respectively, carrying the treating medium and articles being treatedand separated, said tumbling cylinder being provided with an articlereceiving opening at one end and having on its interior a spiralconveyer blade constructed and arranged to keep the articles beingtreated aggregated near said feed opening when the cylinders are rotatedin one direction, and transfer means within said tumbling cylinder forseparating the articles being treated from the cleaning material anddischarging the same to said separating cylinder when said cylinders arerotated in the other direction.

4. In a cleaning and polishing machine, a rotatably mounted cylinderprovided with conveyer means adapted when rotated in one direction toaggregate the material and treating medium and provided with means forsegregating the material being treated when rotated in an oppositedirection, a concentric screening cylinder inclosed by and communicatingwith said tumbling cylinder, and a transfer device establishing materialtransferring communication between said cylinders when rotated in areverse direction.

In testimony whereof I have afiixed my signature.
